When we stay as a family in a Disney resort, we always stay Concierge Level. We have two young boys (4 and almost 6). They are both on the Autism spectrum, so we do it mostly for the convenience, extra "personal" attention, nice lounge to hang out in, and the snacks, which we find AMPLE for about half our day's food consumption. We eat small meals and snacks throughout the day in general, so at WDW or DLR, this works much better for us than doing huge sit down meals, which our boys are just not good at doing.
I love that you can contact a person AT your resort prior to your arrival. They can help you arrange almost any special needs you might have during your stay. The IPO staff at BC went above and beyond for us in March. They were wonderful. Everything we needed, we got. There was no "this is a request, not a guarantee" garbage with them. We NEEDED a daybed so our sons would each have his own bed, they will NOT share a bed with anyone. We were only a party of 4, but the IPO staff assured me that we WOULD have a daybed, no worries. And, we did have one, as well as a beautiful room view upgrade.

We had some special food needs as well, and they bent over backwards to help us out.
I love knowing that someone is looking out for us. When we arrive, I feel like I am coming "home" because the staff already knows so much about us. Our kids can be difficult, but the staff in the lounge and at the desks was always one step ahead of them, trying very hard to head off meltdowns by offering something (a sticker, a taffy, a cookie, etc.) We feel so much more welcome at CL.
I also love not having to go to the front desk. Ever! It's so nice. I love when I need something, I can go for a short walk to the CL desk and be helped by someone who "knows" me, at least by sight if not name. Although, they usually remember your name. They are good.
It's more than the food for us. It's much more. It's an entire experience that you simply don't get by staying non-CL. Don't get me wrong, there's nothing with that either, and when I travel with my friends or sister, we NEVER stay CL, simply because we are park commandos and don't have any special needs or expectations when we go together.
My family trips are MUCH more laid back. More resort time. More relaxing time. And, CL is perfect for that!
